IMPROVEMENT lIN HORSE-POWERS.

Specication forming part of Letters Patent'Na 119,279, dated September26, 1871.

To all whom t may concern:

Be it known that I, JAMns MARSHALL, of the city of New Orleans and Stateof Louisiana, have invented an Improved Horse-Power, of which thefollowing is a full, clear, and exact description, when taken inconnection with the drawing aufA nexed, to which reference must be madeas constituting a part thereof. o A

My improvement relates to horse-powers; and

` it consists ina peculiar construction and arrangementof parts, all ofwhich will be more fully described in the annexed specification,reference being had tothe accompanying drawing.

In the drawing like letters refer to like parts.v

Figure l is a perspective view of my improvey ment complete and readyfor use, with the eXception of the ends of the levers and thedrivingshafts, by which power is transmitted. Fig. 2 is a verticalcross-section of the same.

' ln the drawing, A represents a substantial bedframe, constructed oftimber in any desirable form or manner; or it may be secured to thefloor of a An upright hollow column, B, having an enlarged saddle-base,B', is secured to the bedy frame A by means of bolts c c, and furnishesa bearin g, d, for the driving-gear. To this hollow column B is firmlykeyed the large spur-wheel C, around which the pinion `D revolves whilesimultaneously revolving upon its own axis, thereby imparting motion tothe stud-shaft E, which is stepped in the casting N at its lower end andjournaled therein at its upper end. Upon the upper extremity of shaft Eis keyed the spurwheel F, gearing into pinion G, by which motion iscommunicated to the vertical driving-shaft H. This shaft has itsbearings in the step b on the bed-frame A, and passes through the hollowcolumn B. On shaft H is keyed a bevel-wheel, I,

meshing into the bevel K upon the horizontal sh aft L, which is carriedunder the track to. any

desired place, and from a pulley at its outer end motion may becommunicated to any machinery to be driven. The vertical shaft H isfurthermore provided, at or near its upper extremity, with a pulley orgearing for driving machinery such as is used for ginning cotton,grinding,

thrashing, sawing, Sto.

The great advantages of my improvement over all others hitherto in usewill be readily under stood, as it is very strong andv durable, as wellas compact. It is also not liable to get out of order, and can befurnished at a very small expense.

Having thus described my invention, what I claim, and desire to secureby Letters Patent,

l. The combination, in a horse-power, of the large stationary gear-wheelG upon the i column B with the pinion D, shaft E, gear-wheel F, pinionG, and shaft H, all arranged substantially as and for the purpose setforth.

2. The fixed upright hollow column B having saddle-oase B in combinationwith theshaft H7 gear-wheel C, frame N, and levers M M, all constructedand operated substantially as and for the purpose specified.

- 3. The arrangement of the column B, frame N, gear-wheel O, pinion D,shaft E, gear-wheel F, pinion Gr, shaft H, bevel-wheels I K, andhorizontal shaft L, all constructed and arranged for operation as shownand described, for` the purposes set forth.
